Bold and brazen, that's what he is. He's also trespassing.
Yes, this is my yard, but this is NOT my cat. My cat is strictly indoors because I don't believe in letting domestic cats roam unsupervised - they are simply too efficient at killing wildlife. We have a lot of ground nesters like ovenbirds around here. Cats are pure hell on ground nesters. They are also hard on lizards, snakes, rabbits, rodents...the list goes on. I don't think cats are evil, mind you, they are just excellent hunters and they do what comes naturally.
This male cat showed up a couple of months ago. I've found his tracks on the back porch, I've smelled his...well, you know. He is a clever cat and has proved impossible to catch thus far -- but I'll keep trying.
